Gulper Eel in Action

The team from E/V Nautilus are back, watching the bottom of the ocean for interesting creatures. And here they've found one with their remotely-operated vehicle (ROV) in the deep sea at Papahānaumokuākea Marine National Monument. At first, they don't recognize a gulper eel (Eurypharynx pelecanoides) because they are rarely seen alive and gulping. (via reddit)
